iPS cell technology patents granted in Japan and the United States

Kyoto University has been granted four patents relating to its basic iPS cell technology, one in Japan and three in the United States, the university said Tuesday, Sept. 18. Two of the US patents have already completed patent registration and the remaining two patents are due for registration within a month.

The patent granted in Japan (application no. 2007-550210) relates to basic technology for induced pluripotent stem cells (iPS cells), which were successfully generated as a world first by the research group of Professor Shinya Yamanaka, Director of the Center for iPS Cell Research and Application (CiRA).

One of the three patents granted in the US is a patent (application no. 12/213,035) relating to technology developed by Yamanaka's group. The other two (application nos. 12/157,967 and 12/484,163) are patents assigned to Kyoto University by the US bioventure iPierian with effect from January 27, 2011.

Kyoto University has already obtained three Japanese patents relating to basic iPS cell technology. The granting of the new patent brings the total number of Japanese patents to four. In the US, where CiRA has to date acquired three patents relating to basic iPS cell technology, the newly obtained patents bring the total number of the US patents to six.

CiRA believes that the acquisition of the four new patents will contribute, in both Japan and the US, to creating an environment in which a large number of enterprises can feel confident about undertaking iPS cell research, screening of drug candidate substances, and other elements of applied research.

With the ambition of realizing medical application of iPS cells at the earliest possible date, Kyoto University is committed to continuing to promote widespread interest in iPS cell technology and related research.
